11. Electronic spin states are more complex for transition metals. 12. This ? splitting is generally large enough that these complexes do not exist as high-spin state . 13. Spin crossover refers to the transitions between high to low, or low to high, spin states . 14. As a result, the different nuclear spin states have different energies in a non-zero magnetic field. 15. However, in the case of d 8 complexes is a shift in geometry between spin states . 16. Furthermore, it means that a lepton can have only two possible spin states , namely up or down. 17. As a result of having non-paired electrons in both spin states coupled together, this compound exhibits antiferromagnetism. 18. For example, a spin-1 / 2 particle would have f = 2, one for each spin state . 19. Therefore, Raman spectroscopy can be used to identify which spin state is predominant in a SCO complex. 20. The spin state may depend on location.
